Clay incorporated ruthenium oxide nanocomposite for electrochemical, sensor, optical, photocatalytic and antioxidant studies

Abstract

In the current study, Clay incorporated RuO2 nanocomposite was prepared employing simple refluxing method. The synthesized Clay/RuO2 is then Characterized using XRD, SEM, FTIR, EDAX and UV-Visible spectroscopy. The results demonstrate that Clay/RuO2 can effectively facilitate the photocatalytic degradation of Methylene blue (95%) with excellent performance. An electrochemical analysis of the prepared material was conducted using graphite electrode paste in 3 M KCl electrolyte, revealing its remarkable redox potential output as determined by cyclic voltammetry (CV). Furthermore, the material revealed efficiency as a sensor for Cow urine, Cd and Hg sensors from an aqueous solution. Clay/RuO2 was also evaluated for its ability to detect these three sensors in an aqueous solution. The synthesized Clay/RuO2 nanocomposite was utilized for optical and antioxidant activity. The results revealed that it possesses effective free radical scavenging activity of approximately 91%, indicating strong antioxidant activity by showing IC50 value around 112.11 mg/mL.
